If people threaten to kill you for years and you die in a suspicious matter that is far from proof that the two are even remotely related.
Let the evidence guide us to an understanding of what has happened, let us not put an interpretation on the events merely because we "feel" it must have happened a certain way.
I haven't claimed at any point that there is proof Hastings was murdered.
When someone gets an ample number of death threats, and they die in an even remotely suspicious manner, it is not a conspiracy to consider that one of those threats may have become actual. It's that simple.
McChrystal's staffer told Hastings directly: if you write something we don't like, we will kill you. Where's the conspiracy in suspecting that staffer of murder, given he threatened to murder Hastings?
